Setting Up an RFC-2544 Test Suite

When you click in this field, a dialog pops up. You can select a device from the Skylight orchestrator inventory.

A maximum of one test suite can be created per device.

• Layer-2: Y.1731 LBM frames.
• Layer-2 Accedian: Y.1731 LBM frames marked with the Accedian Ethertype.
• Layer-2 generic: Special Y.1731 OpCode frames to be used only with loopback devices based on the MAC- address swap.
• Layer-3 generic: Layer-2 frames with a generic Layer-3 (UDP) payload. Only to be used with loopback devices based on the MAC-address swap.
• Layer-3: UDP segments to perform a test across a multi-layered network.

When strict failure is enabled, OOO or duplicate frames/packets will cause a test to fail, even if all frames/packets were received.

When strict failure is disabled, the unit tolerates OOO and duplicate frames/packets. If all frames/packets were received, the test is marked as passed.

Notes: Layer-3 generic traffic is available for the RFC-2544 traffic generator and test suite. It is unavailable for Y.1564 SAT.

IP multicast traffic is available for the RFC-2544 traffic generator. It is unavailable for the RFC-2544 test suite and Y.1564 SAT.

To select a port:

• Click in this field. An ellipsis button is displayed.
• Click on the ellipsis button. A list of available ports for the Near-end device is displayed.
• Select a port and click OK.

Note: Applies to Layer-3 traffic only.

To select a device:

• Click in this field. An ellipsis button is displayed.
• Click on the ellipsis button. A list of available devices is displayed.
• Select a device and click OK

Notes: Applies to Layer-3 traffic only. For reporting to work properly, you must set the port to a value in the range of 0 to 65,535. However, you must not set the destination port value to 8,793 because this is Accedian's proprietary port number. For information on destination ports default values, see Network Requirements — TCP/UDP Ports in the documentation for the selected device.

A port cannot be defined as the UDP port here if it is already being used for any of the following features on the selected far-end device:

• A Layer-3 PAA instance
• TWAMP
• Layer-3 RFC-2544 Generator
• Layer-3 RFC-2544 Test Suite
• Layer-3 Y.1564
• SAT Protocol.

This encapsulates all frames with one VLAN header.

If the VLAN 1 header is enabled, the packet size increases by 4 bytes. For example:

• If the packet size is set to 64 and the VLAN 1 header is not enabled, the traffic generator will send packets of 64 bytes.
• If the packet size is set to 64 and the VLAN 1 header is enabled, the traffic generator will send packets of 68 bytes.

When enabled, all test frames are encapsulated with the specified VLAN ID.

Possible values are:

• C-VLAN: 0x8100
• S-VLAN: 0x88a8
• S-VLAN: 0x9100
• T-VLAN: 0x9100

Note: Applies only when the VLAN 1 header is enabled.

Note: Applies only when the VLAN 1 header is enabled.

In order to use two VLAN headers, both VLAN 1 and VLAN 2 headers must be enabled.

If VLAN 1 and VLAN 2 headers are both enabled, the packet size increases by 8 bytes. For example:

• If the packet size is set to 64 and both VLAN 1 and VLAN 2 headers are enabled, the traffic generator will send packets of 72 bytes.

Note: Applies only when the VLAN 2 header is enabled.

Possible values are:

• C-VLAN: 0x8100
• S-VLAN: 0x88a8
• S-VLAN: 0x9100
• T-VLAN: 0x9100

Note: Applies only when the VLAN 2 header is enabled.

Note: Applies only when the VLAN 2 header is enabled.

This parameter also applies to the delay and delay variation test, as well as to the frame loss test.

Range: 1 to 1,000 Mbps. In steps of 0.125 Mbps for rates from 0 to 12.5 Mbps, and in steps of 1 Mbps for rates greater than or equal to 13 Mbps.

You must select a Minimum Rate that does not exceed the capacity of the outgoing port being used for the test suite. Failure to do so may produce inaccurate results.

This parameter also applies to the delay and delay variation test, as well as to the frame loss test.

Range: 1 to 1000 Mbps. In steps of 0.125 Mbps for rates from 0 to 12.5 Mbps, and in steps of 1 Mbps for rates greater than or equal to 13 Mbps.

You must select a Maximum Rate that does not exceed the capacity of the outgoing port being used for the test suite. Failure to do so may produce inaccurate results.

Note: The actual transmission rate (TX rate) used during the throughput test will not necessarily match the value of the Maximum Rate parameter, since the transmission rate depends on the results obtained from the binary search algorithm.

This parameter also applies to the delay and delay variation test, as well as to the frame loss test.

The throughput test begins by determining the maximum rate at which the test settings yield no lost frames.

For example, to measure the quality of a wire-speed GigE circuit, enter a Minimum Rate of 800 Mbps, a Maximum Rate of 1000 Mbps, a Step Size of 10 Mbps and a Binary Duration of 2 seconds. The unit then performs a binary search between 800 Mbps and 1000 Mbps for 2 seconds using 10 Mbps increments in order to determine the highest rate at which the test can be performed without failing.

Once the maximum rate is determined, the throughput test starts executing the actual test, which involves sending frames according to selected Frame Size settings for the duration specified by the Trial Duration.

(for throughput test)

Range: 1–1,800 seconds

Default: 60 seconds

(for throughput test)

Default: 0, which means a target of no frame loss is tolerated when defining full throughput, i.e. losing a single frame will cause the test to fail.

(for throughput test)

Note: The frame size you select must be smaller than the port's MTU. Selecting a higher frame size will prevent you from running the test.

The frame loss test verifies that no frames are lost when the current test settings are used. The unit starts at the maximum rate defined in the throughput settings section, then steps down by the value entered in the Step Size parameter of the Frame Loss settings.

Two consecutive rates must have no frame loss in order to successfully pass this test. For example, if the Unit Under Test (UUT) is able to perform full wire-speed at GigE, the test runs at 1000 Mbps and 980 Mbps (for a Step Size of 20 Mbps). Both tests must yield no frame loss in order to be successful, otherwise a lower rate will be tested.

Ensure that you have entered all required parameters in the throughput settings section, since some of these parameters also apply to the frame loss test.

(for frame loss test)

Range: 1–1800 seconds

Default: 60 seconds

The frame loss test also uses the Maximum Rate, Minimum Rate and Fine Stepping values set in the Throughput Settings section.

(for frame loss test)

Note: The frame size you select must be smaller than the port's MTU. Selecting a higher frame size will prevent you from running the test.

Once a wire-speed rate with no frame loss has been defined by the throughput test, the delay and delay variation test measures the latency and jitter at that specific rate.

Ensure that you have entered all required parameters in the throughput settings, since some of these parameters are required by the delay and delay variation test.

(for delay variation test)

Range: 1-1800 seconds

Default: 120 seconds

The delay and delay variation test also uses the Maximum Rate, Minimum Rate and Fine Stepping values set in the Throughput Settings.

(for delay variation test)

Default: 0, which means a target of no frame loss is tolerated when defining full throughput, i.e., losing a single frame will cause the test to fail.

(for delay variation test)

Note: The frame size you select must be smaller than the port's MTU. Selecting a higher frame size will prevent you from running the test.

The back-to-back test sends a minimum of 50 repetitive bursts of frames with minimum inter-frame gap (line rate) according to the test settings. For this test to be successful, the network being tested must not lose any frames after a burst. A two-second pause is inserted after each burst.

Ensure that you have entered all required parameters in the throughput settings, since some of these parameters are required by the back-to-back test.

(for back to back test)

Range: 1–10,000 milliseconds

Default: 2,000 milliseconds

(for back to back test)

Default: 50 bursts

Range: up to 100 bursts

(for back to back test)

Note: The frame size you select must be smaller than the port's MTU. Selecting a higher frame size will prevent you from running the test.
